Prevalence of hearing loss and tinnitus after childhood cancer treatment: a Danish nationwide registry-based study

Despite rising survival rates and high-quality health data available - no large-scale study has mapped the full Danish Childhood Cancer Survivor population with auditory late effects. AIMS/OBJECTIVES: This study aimed to estimate the prevalence of auditory late effects among Danish children and adolescents diagnosed with cancer in a national register-based study.

Audiologists managing childhood cancer survivors should maintain heightened vigilance for hearing loss and tinnitus, as this registry study quantifies prevalence at a national scale and supports routine long-term audiological follow-up in this population.

Rising childhood cancer survival rates mean a growing cohort of patients at risk for treatment-related (ototoxic) hearing damage, making accurate prevalence data essential for shaping survivorship care guidelines and audiological monitoring protocols.

1. 01Nationwide Danish registry study examining hearing outcomes in childhood cancer survivors.
2. 02Maps prevalence of both hearing loss and tinnitus following childhood cancer treatment.
3. 03Leverages high-quality national health registry data for population-level estimates.
4. 04Rising cancer survival rates increase the clinical relevance of long-term ototoxicity monitoring.
5. 05Findings could inform survivorship guidelines for audiological follow-up.
